The shape of the molecule and The electronegativity differences of atoms in the molecule
Check the molecular geometry to determine if the molecule is asymmetrical. If the molecule has a symmetrical shape, it is likely nonpolar. If it is asymmetrical, check for polar bonds and the overall molecular polarity.
there is no such thing as a non polar end, the whole molecule is either polar or nonpolar. in a polar molecule, the negative end has the purpose of being attracted and combining with the positive end of another polar molecule; if that's what you meant.
There is no such thing as semi-permeable molecules.
the thing that determines it is the type of molecules that are in the substance
it is a good thing how told you that

No, ionic and polar are not the same. Ionic bonding involves the transfer of electrons between atoms to create charged ions, while polar covalent bonding involves the unequal sharing of electrons between atoms leading to a partial separation of charges within the molecule.
wouldn't it be moving?
A diamond. Also the shape of a molecule can only affect physical properties.
No, of course there is no such thing as Club Evil Polar Bear, silly!
Not really. The closest thing would be molecules with long hydrocarbon chains such as decanal (C10H20O) with the C-O bond being polar. The carbon-hydrogen bonds are technically polar as well, but this polarity is very weak.
No.
